Need help asap! Please look a/f strange issues
Ok ppl, I have some strange issues with my a/f readings. After installing an intake manifold and tb off a N1 , to my SR20VE, the a/f readings on idle are way off like 16.5:1. Now, Using all kinds of fuel management as safc and AEM Fic, the only thing I could do was to make it stoich for a couple of seconds and then it comes back to 16.5:1. This thing drives me crazy, I mean it's a steady 16.5 and I put a +10 or +20 % to the injectors or the maf sensor. It goes down to 14 and after 10-20 seconds it climbs slowly to 16.5! Now what the hell is this? No CELs whatsoever. I don't know what to do... Other than that, the safc seems to respond at any other modifications on half throttle but when I use full throttle, the car again doesn't respond to whatever fuel I may add. This happens to both cases, using safc, fic, you name it....
